If they work, they're great, but it's best not to plan for parking. I don't mean turn off the car, I mean put it in park; it just turns off. In addition, the same reaction can occur when driving at low speeds (e.g. in the neighborhood). Now you can figure out how to turn them back on while driving...yay! And customer service can provide amazing wit and condescending names but no real help so good luck!
